IMPROVEMENT IN CORN-DROPPERS.

Specification forming part of Letters Patent No. 145,552., datedDecember 1G, 1873; application filed July 26, 1873.

To all whom it may concern:

Be it known that we, ROBERT M. BOWMAN and WILLIAM H. BowMAN, of London,in the county of Madison and State of Ohio, have invented a new andImproved Corn-Dropper, of which the following is a specification Ourinvention consists of a hopper-bottom having the hole for dropping thegrain into it, with a supplementary slide for closing the hole arrangedon its under side, said bottom being arranged to slide forward and backto bring the hole under the grain in the hopper, and

then move it beyond the cut-off to the place of delivery, and at thesame time dpenthe hole by carrying the supplementary slide against astop, which holds it against moving with the hopper-bottom as soon asthe hole has passed beyond the cut-olf, while the bottom continues asfar as the width ot' the hole, and then goes back for another charge,the supplementary slide being closed during the back movement by aspring. The arrangement is designed to prevent the choking and cloggingcommon to most droppers in use.

ber behind the cut-oit1 D. F is the supplementary slide on the underside of the hopperbottom for closing the hole. Gis the stop forarresting the 'supplementary slide, and H is the spring for closingslide F. The hopperbottom A is arranged to slide forward and back by anysuitable means, and carries the hole C under the cut-off into the hopperto be tilled, said hole being closed at the time by the slide F, andforming a pocket, which, being filled, carries the grain contained in itbeyond the cut-off into the recess E; the pocket then opens by the slideF coming against the stationary stop G, while the hopper-bottomcontinues to move until the hole is completely opened; the bottom thengoes back, and the hole is closed during the iirst part of the backwardmovement.

It will be seen that there is little or no chance for the hole to clogwith the grain, and in case it does the grain in the pocket will becarried forward and backward with the slide, but cannot stop it.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- The slide-bottom A, having the drop-hole O,combined in a corn-dropper with the auxiliary spring-slide F, the twoarranged to operate together in the manner and for the purposedescribed.
